Embodiment 1
[0031] An embodiment of the present invention provides an image clustering device, figure 1 is a schematic diagram of the structure of the image clustering device of the embodiment of the present invention. Such as figure 1 As shown, the image clustering apparatus 100 includes: a first clustering unit 101 , a second clustering unit 102 and a fusion unit 103 .
[0032] Wherein, the first clustering unit 101 performs clustering based on visual features to multiple images to obtain the first set; the second clustering unit 102 performs clustering of the link structure to multiple images to obtain the second set; the fusion unit 103 The result of image clustering is obtained by fusing the first set and the second set by visual feature information and link structure information.
[0033] In this embodiment, a plurality of images may be given first, and the images may be geotagged images. For example, given N images I={(x 1 , g 1 ),(x 2 , g 2 ),…,(x n , g n )}, I i =(x i ...
Embodiment 2
[0042] On the basis of Embodiment 1, the embodiment of the present invention further provides an image clustering device, and the same content as Embodiment 1 will not be repeated.
[0043] figure 2is another schematic diagram of the structure of the image clustering device according to the embodiment of the present invention. Such as figure 2 As shown, the image clustering apparatus 200 includes: a first clustering unit 201 , a second clustering unit 202 and a fusion unit 203 . Such as figure 2 As shown, the image clustering apparatus 200 may further include: a classification unit 204, which clusters a plurality of images according to the classification information, so as to filter the plurality of images.
[0044] In this embodiment, the classification information may be image additional information, such as GPS information, but the present invention is not limited thereto, and may also be other classification information. The classification unit 204 can cluster the i...
Embodiment 3
[0074] An embodiment of the present invention provides an image aggregation method, which corresponds to the image aggregation method in Embodiment 1, and the same content will not be repeated here. Figure 5 is a flow chart of the image clustering method of the embodiment of the present invention, such as Figure 5 As shown, the image clustering method includes:
[0075] Step 501, performing clustering based on visual features on multiple images to obtain a first set;
[0076] Step 502, performing link structure clustering on multiple images to obtain a second set;
[0077] Step 503, merging the first set and the second set by using visual feature information and link structure information to obtain an image clustering result.
[0078] In this embodiment, step 502 performing link structure clustering on multiple images to obtain the second set may specifically include: constructing a KNN graph for multiple images based on image visual features, and performing structured clust...
